Title: Improvements in apparatus for circulating the water in a steam boiler
IPC: F22B37/34
Filed: 1932-11-25
Abstract: 402,248. Promoting circulation in steam boilers. INOKUCHI, T., 1227, Mikagecho, Muko-gun, Hyogoken, Japan. Nov. 25, 1932, No. 33451. Convention date, Dec. 2, 1931. [Class 123 (ii).] Water circulation is promoted by the incoming feed which is supplied through two pipes, one directing jets towards the front from a transverse pipe 8 in the upper part of the boiler, and the other directing a jet towards the rear through a pipe 9 opening in the lower part of the boiler. The lower jet opens into an injector 12, which draws water down pipes 13 opening into the upper and lower parts of the boiler.
Patent GB-324736-A (GB)
Title: Improvements in and relating to grabs
IPC: B66C3/08
Filed: 1928-11-15
Abstract: 324,736. Barnard, D. J. Nov. 15, 1928. Grab-buckets.-Relates to scraper grabs having a span when open considerably greater than the height of the closed grab. A scraper grab in which the spreader arms 3, 4, are formed rigidly with the scoops and are pivoted on separate spindles 5, 6 in the grab-head is constructed for operation by a single chain or rope. The hauling rope 27 is led past a guide sheave 29 in the grab-head and around sheaves 26, 25 mounted in the spreader arms and is made fast at 27x. As shown the spreader arms are geared together by toothed segments 9. Links 10 pivoted to the spreader arms at 11 and geared together at 15 are pivoted in brackets on the cross-beam 17. The cross-beam is suspended from the grab-head by chains 19 passing round sheaves 21 mounted on the beam in brackets 22. One end of each chain 19 is anchored at 20a in the grab-head, and the other end is secured at 23 to a ring member 24 carrying pivoted hooks 42 which co-operate with a suspended ring 43 for discharging the grab. A ring 45 loose on the member 24 normally rests upon arms 48 of the hooks 42 keeping the hooks in position to engage over the suspended ring 43 when the closed grab, Fig. 1, is raised by the rope 27. On then paying out the rope 17, the weight of the grab is transferred to the chains 19, as shown in Fig. 4, so that the grab opens, the links 10 spreading apart until past dead centre and the cross-beam 17 entering between faces 30, 31 on the upper ends of the spreader arms. On now hauling in the rope 27 the crossbeam is gripped and the open grab is lifted. In this position of the cross-beam, the brackets 22 in which the sheaves 21 are mounted engage and lift a thimble 36 having limited vertical play on pins 38 in the grab-head. When the open grab is lifted up so far as to engage the ring member 24, as shown in Fig. 8, the thimble 36 engages pins 46 on the ring 45 and lifts this ring so that the hooks 42 fall outwards clear of the suspended ring 43 and the open grab can be lowered. When the open grab rests upon the ground and the rope 27 is slack, the links 10 are free to fall past the dead centre, sufficient play at the pivots 11 being provided by slots in the links. The chains 19 now being slack, the cross-beam 17 falls clear of the locking surfaces 30, 31 and on hauling-in the rope 27 the grab is closed.

Title: Improvements in or relating to Colour Television Cameras.
IPC: H04N9/09
Filed: 1967-07-21
Abstract: 1,187,848. Colour television. THOMSON C.S.F. 21 July, 1967 [29 July, 1966], No. 33724/67. Heading H4F. To reduce distortion due to lack of symmetry in the three primary colour signal channels in a colour television camera, the component colour signals are subjected to time division multiplexing at a frequency above the highest frequency in the bandwidth of the component colour signals, the resultant signals are fed to a common signal correction circuit (e.g. for gamma correction, for varying the amplitude of the signals, and for establishing the black level) and the corrected output from the correction circuit is fed to a decoder operating in synchronism with the time division multiplexing to deliver reconstructed corrected component colour signals. The time division and decoding is effected by electronic switches, one for each component colour signal, which are controlled by sequences (one for each switch) of sampling pulses of the same repetition frequency but time shifted i.e. delayed, with respect to each other. Correction of the luminance signal may also be effected.

Class 40(8) [Also in Group XL(a)] The inductance of loop 23 coupling a coaxial line 9, 18 to a cavity 1, of e.g. a klystron, is compensated by a capacitative discontinuity in the form of a slug 24 which may be attached to the inner conductor 9. The outer conductor 18 is formed with an oval bore 21 communicating with the cavity at one end and, at the other, with a circular bore 19 extending in the direction of the major axis of the oval bore. This arrangement facilitates assembly. The cavity 1 is vacuum-sealed by an annular window 14 which is described and claimed in Specification 863,470. The resonant frequency of the coupling is so arranged in relation to the tuning range of the cavity that an increase in coupling is effected as the resonant frequency of the cavity is increased. This compensates a corresponding decrease in beam coupling.
